Drones Can Now Be Used To Transport Laboratory Specimens To Remote Medical Clinics

Drones have already delivered medicine, but soon they may also deliver blood samples and other laboratory specimens.

They found out that human blood samples remain stable when airlifted by small drones.

The researchers believe, in the future, that this form of delivery could give millions of people in rural and economically poorer areas better access to diagnoses and treatments.

Led by Johns Hopkins’ Dr. Timothy Kien Amukele, the scientists started with 56 healthy adult test subjects, drawing six blood samples from each person. Half of those samples (representing each person) were then carefully packed into an Aero fixed-wing drone made by 3DRobotics, and flown around in it for periods ranging from six to 38 minutes. The air temperature was around 70º F (21º C), and the drone didn’t exceed an altitude of 100 meters (328 ft).

From there, they were all subjected to the same 33 tests, which constitute the most commonly-performed blood tests.

Initially, there were concerns that acceleration upon take-off and vibrations caused by rough landings might affect the samples. As it turned out, though, the test results for individual test subjects’ flown and unflown samples were virtually the same. In some cases, there were differences when testing for total carbon dioxide levels, although this could simply be due to the amount of time that the blood sat around before being analyzed.

Amukele now hopes to conduct field tests in Africa, where clinics are often located long distances from decently-equipped labs.

A drone could go 100 km in 40 minutes. They’re less expensive than motorcycles, are not subject to traffic delays, and the technology already exists for the drone to be programmed to ‘home’ to certain GPS coordinates, like a carrier pigeon,” Amukele said.
